Sagot :
D = (1/2 + 3/4 ) / 35/-16
D = (5/4) X -16/35
D = (5X-16) / (4X35)
D = (-80) / 140
D = - 40/70
D = - 4/7 !!
Voila!
Calculer est donner sous forme de fraction irréductible :
D= (1/2 + 3/4) : 35/-16
D = (1/2 + 3/4 ) / 35/-16
D = (5/4) X -16/35
D = (5X-16) / (4X35)
D = (-80) / 140
D = - 40/70
D = - 4/7 !!
Voila!
